Okay, I have an '06 F-150 Supercrew with the 4.6L however I am mounting my brake controller in that little cubby hole undernead the cup holders in the dash, what I am trying to do, is come in from the back and drill a hole for the wires, however I don't want to screw up my dash, So I am wondering what is the best way to get to that part, does anyone know?
